The intention behind this kind of event is awesome. Focus on getting the founders and the funders to talk (whilst allowing serious service-providers to come and catalyse the reactions between these two parties) and you're bound to create some awesome companies.
Thanks pal. Really hope we see a lot of y-combinator folks sign up to pitch! Note: you don't have to be based in LA or California to present... we'll take a great idea from anywhere in the world.
